CHARLES H. REINISOH, OF NEW YORK, N. Y.

MACHINE FOR MAKING AND TWISTING CHAIN-LINKS.

SPECIFICATION forming part of Letters Patent No. 310,317, dated January6, 1885.

' Application filed April 18, 1884. (No model.) i

To aZZ whom it may concern:

Be it known that I, CHARLES H. RErNIsoH, of the city, county, and Stateof New York, have invented a new and Improved Machine for Cutting,Bending, and Twisting Links for Chains, of which the following is afull, clear, and exact description.

My invention relates to a machine for making quartern chain-links, whichmachine comprises a revolving mandrel, over which the links are shaped,stationary and movable cuttingedges for cutting the links, and means forgrasping and holding, and at the same time twisting, the links.

The invention consists of the means for revolving the mandrelintermittently, of the means employed for cutting and grasping the linkswhile the twist is being formed, of the means employed for twisting thelinks, of the employment of a holding-bar to act in connection with themain cutting-lever, whereby the holding-bar will automatically adjustitself to anyirregularityin the rod or wire from which the links arebeing formed, of the means for operating the main cutting-lever andtwister; also, of the general construction, combination, and arrangementof the parts of the machine, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of my invention. Fig. 2 is a broken sideelevation of the same. Fig. 3 is a sectional plan view, taken on theline w x of Fig. 2. Fig. 4 is a sectional elevation, taken on the line3/ 9/ of Fig. 2. Fig. 5 is a perspective view showing the stationarycutter and guide for the rodor wire from which the links are cut. Fig. 6is a side elevation of the mandrel removed from the machine. Fig. 7 is afront elevation of the mandrel, showing the rod or wire from which thelinks are cut wound around it, and held by the clamp-wheel; and Figs. 8and 9 show, re

spectively, side and end views of the twister removed from the machine.

A represents the main frame of the machine, constructed of cast iron,preferably, and with the table A, of such appropriate size and form asto properly receive and support the operating mechanism.

B is the main shaft, on which are fixed the pinions a a, and the twopulleys bone fast and one loose. The pinion a meshes with the largegear-wheel C, which has thelarge cam c, the short segmental rack d, andouter cam, 0, formed upon its inner surface for operating, respectively,the cutting-lever D, the toothed segmental bell-crank E, for turning thetwister F, and the lever G, for raising andlowering the twister F, allin the manner and for the purposeshereinafter described, The pinion ameshes with the intermediate gear, H, and this gear I-I meshes with thegear-wheel I, placed loosely upon the short heavy shaft I, journaled inthe heavy boxes I I.

Keyed fast to the shaft I, between the gearwheel I and the journal-boxI, is the disk J. This disk J is provided with the pivoted dog f, whichis pressed toward the gear-wheel I at one end by the springf, forcausing the lug f of the dog to engage with the lugf formed upon thegear-wheel I, for locking the wheel I and disk J together.

Upon the journal-box I is formed or secured the toe 9, against which theprojection f* of the dog f is adapted to strike at the proper time fordisengaging the projection f of the dog f from the lug f on thegear-wheel I, thus permitting the wheel I to make a complete revolutionindependently of the shaft I and disk J before looking again with thedisk J. In this manner, while the wheel I revolves continuously, anintermittent rotary motion is imparted to the disk J and shaft I, andalso to the mandrel K, which is attached to the inner end of the shaft Iby the square shank 7i? ofthe mandrel entering a corresponding socketmade in the shaft, as shown clearly in Fig. 6. The rod or wire L, fromwhich the links are cut, is fed to the stationary guide and cutter M ofthe machine over the said mandrel K, and the mandrel is made ellipticalin form in crosssection, as shown in Fig. 7, for shaping the links. Therod or wire L, as it coils around the mandrel K, is made to conform tothe shape of the mandrel by the roller h, under which the wire or rodpasses, which roller h is journaled upon the pivoted arm h, which ispressed downward by the strong spring h-, the pressure of which may beregulated by the thumbscrew h, as will be clearly understood from Fig.2.

m is the cutting-edge of the stationary guide and cutter M. The guideand cutter l\I is held in horizontal position and so as to stand at anacute angle with the mandrel K by the keepers M M, bolted to the topplate, A, of the frame of the machine, and these keepers may be madeadjustable forwarying the angles of the guide and cutter, and the guideand cutter M is made trough-shaped and diagonal'at its cutting end m,and is so placed in the machine that the diagonal end an standspartially under the mandrel K, so that the edges m m serve to force thecoils of the wire or rod L off from the mandrel K, and also to properlyspread the coils so that the knife Z, secured to the short arm (Z of thecutting-lever D, may enter between the coils. so as to act against thecutting-edge m for cutting the links N one by one from the wire or redL, as will be understood from Figs. 3 and 5. The cutting-lever D ispivoted upon the stud j, and its main long arm (Z is adapted to beforced outward,

- ter twist or turn to the link.

causing the knife Z to approach the cutting edge on by theabove-mentioned cam 0, formed upon the large gear-wheel O, and isadapted to be drawn inward by the spring 0, which acts through thetransversely-arranged bar P, to be hereinafter described. After eachlink N is cut from the rod or wire L by the outward movement of the longarm d of the cutting-lever D, the ends of the link are grasped betweenthe end a of the swinging holding-bar Q, and the face of the knife Z,which will hold the link firmly in vertical position, as shown in Fig.2, until the twister F descends upon the folded end of the link, and isturned by means described below, for giving a one-quar- After the twisthas been formed in the link, the machine be ing in continuous operation,the cam c on large wheel 0 will have passed the end of the I long arm (Zof the cutting-lever D, leaving it free to the action of the spring 0,which will act to draw the transverse bar 1?, the end Z1 of theholding-bar Q, together with the arm (Z of the cutting-lever D, from theposition shown in Fig. 3 to that shown in Fig. 1,wl1ich movement willrelease the link N and permit it to drop down through the machinecompleted that is, formed and twisted. The holding-bar Q is divided atits rear end to form the arms 7.: k, and is placed upon the hub Z, whichfits loosely in a socket made in the top plate, A, so as to be adaptedto turn therein, and the hub Z is transversely screw-tapped to receivethe screw-bolt Z. The point end of this bolt Z is reduced in size, andthe reduced portion is passed through the lug Z formed upon the underside of the bar Q, and riveted, as shown in dotted lines in Figs. 1 and3 and in full lines in Fig. 2, so that by turning the screw-bolt Z tothe right or left, the bar Q will be forced forward or backward, beingguided in its movementby the arms kk,wliich pass either side of the hubZ. \Vhen the proper longitudinal adjustment of the bar Q is obtained byturning-screw Z, the bar Q will be made fast to the stud Z by turningdown the nut Z, placed upon the upper reduced and screw-threaded portionZ of the hub Z, which will lock the bar Q and the hub Z securelytogether. The holding-bar Q is yoked to the cutting-lever D by theabove-mentioned transversely-arranged plate 1?, which is connected withthe holding bar Q by the stud 0, formed upon the bar P entering a hole,0, made in the holding -bar Q, and bar Q is yoked with the cutting-leverD by the flange 1) and screw p passed through the flange 2), so that itsinner end rests against the outer edge of the cutting-lever D, asclearly shown in the drawings. The opposite end of the bar P is formedwith the hook p for connection with the spring 0, the office of whichspring, as above described, is to return the bar P. and with it theholding-bar Qand cut ting-lever D, to their original position after thecam 0 passes the end of the cutting-lever D. The end a of theholding-bar Q is made slightly diagonal, and this bar being connected tothe cutting-lever D by bar P, it follows that when the lever D is forcedoutward by the cam c the front end, a, of the bar Q will be drawnforward (the bar turning the hub Z) to stand in front of and parallelwith the knife Z of the cutting-bar D. By adjusting the screw Z thespace between the end a of bar Q and the knife Z may be increased ordiminished as required, according to the size of the rod or wire L fromwhich the links are to be cut, and, owing to the direct longitudinalmovement of the bar Q, caused by turning the screw Z, the properparallelism between the end a and the knife Z will always be maintainedat the time of cutting the link. The end a of the bar Q being held infront of the knifeZ at the time of cutting the link, the instant thelink is cut off from the coil by the knife Z acting against thecutting-edge m of the stationary guide and cutting-bar M, the link willbe firmly grasped between the end n and the knife Z and held as in avise until the operation of twisting the link (yet to be particularlydescribed) is performed, the holding of the parts in this graspingposition being effected by the concentric surface 0 of the cam 0. By theoutward movement of the cutting-lever D, effected by the abrupt edge eof the cam c, the outer edge of the lever D becomes an inclinedhorizontal plane, along which the point end of the regulating-screw pslides until it finds its own seat,which will be at the point where thelink N becomes firmly held, be it large or small in diameter, so thatthe gripping devices for the links in this manner become automaticallyadjustable to any irregularity in the thickness of the wire or red L.The twister F is made square with the claw q at its lower end forreceiving the link, and it is form-ed with the flange g at its upper endfor resting upon the fingers 1' 7 of the lever G, as shown lIO clearlyin Figs. 1 and 2. The square portion of the twister is placed loosely ina square passage made through the collar Rheld loosely in the ring S,formed at the outer end of the overhanging'bracket T, which holds thesaid collar It and twister F above the stationary cutting-edge an. Thecollar 1% is formed or provided with the flange 8 to prevent it fromdropping through the ring S, and also with the arm U, which is connectedby the connectingrod or pitman V to the segmental bell-crank E, abovementioned, which crank is pivoted upon the stud if, so that the teeth 0thereof will be engaged by the rack (7, formed upon the large wheel 0for causing the bell-cran k lever E to turn the collar R and twister Fat the proper time to twist the link N. The movement of the segmentalbeltcrank R will be against the tension of the spring \V, which will actto return the bell-crank E, collar R, and twister F to their normalpositions after the rack d passes the segmental teeth 6 of thebell-crank E, as will be understood from Figs. 1 and 2, The lever G isfulcruined upon the same stud 2- that the bell-crank E is pivoted upon,and the end 0 of the lever is adapted to be depressed by theabove-mentioned cam 0 formed at the edge of the wheel 0 for raising andlowering at the proper time the twister F, so that the claw 1 thereofwill engage with the folded end of thelinkN immediately after it is cutoff from the rod or wire L, and while the link is held by the knife 2'and holdingbar Q, and while the twister is being turned for forming thetwist or turn in the link.

The operation of the machine is as follows: Power being applied to thefast driving-pulley b to cause the main shaft B to be slowly revolved inthe direction of arrow No. 1, the pinion a, meshing into theintermediate gear, H, and this gear, with gear-wheel I, will causethelatter to revolve in the same direction with the shaft B, while thepinion a, meshing directly with large gear-wheel C, will cause this gearto revolve in the opposite direction-in the direction of arrow No. 2-and this gear 0 is of such size relative to the size of the gearwheels III a that it makes but one revolution while the gear-wheel I makes twocomplete revolutions. The rod or wire L to be made into links is firstgiven a few turns on a handmachine and is then slipped over the mandrelK under the p ressure-roller h, which is brought down firmly upon thefirst coil of the rod or wire by turning down the thumb-screw 2r. Theslow motion given to the loose cogwheel I will bring the lug f thereofin contact with the projection f ofthe dogf, which will cause the disk Jand mandrel K to perform one revolution, winding one link upon themandrel and one link off into the guide M between the cutters. The dogf,by the action of the toe 9 upon projection f, then releases the lug fthus permitting the loose cog-wheel I to make another revolution whilethe disk J and man drel K remain at rest. The instant the lugf passesthe dog f the abrupt surface 0 of the large cam 0, formed upon the largegear-wheel G, will force outward the main arm (1 of the cutting-lever D,causing the knife 13 to ap proach and pass the stationary cutting-edgein, causing the link wound off from the wile or rod L to be out off.W'ith the outward movement of the main arm d of the cutting lever D theholdingbar Q, will be brought forward by the transverscly-arranged bar1?, so that as the knife i passes the stationary cutting cdge m the linkN will be grasped and firmly held between the knife 2' and the end a ofthe holdingbar Q. At this time the concentric surface 0 of the cam 0will have reached the arm (1 of the cutting-lever D, so that while thisconcentric surface 0 of the cam c is passing the lever D the knife t andbar Q, will re main at rest, holding the link. At the time the link iscut, or a little before, the cam e on wheel 0 will depress the end 6 ofthe lever G, which will elevate the opposite end of the said lever andcause it to raise the twister F in the collar R and to hold the twisterabove the link, and during the interval of rest of the bars D and Q andknife z while they hold the link the cam 0 will pass the end 6' ofthelever G, which will permit the twister F to drop down in the collarB, so that the claw q of the twister will rest upon and engage with thefolded end ofthe link, as shown clearly in Fig. \Vhile the twisterremains in this position, engaging the link, the rack (1, formed uponthe large wheel 0, will come in contact with the teeth act thehell-crank E, causing the bell-crank, acting through the connectingrodV. lever U, and collar It, to give the twister F a one quarter turn,which will put the required twist in the link. This being accomplished,the cam-face 0 will have passed the main arm (I of the cutting-lever D,whereupon the spring 0 will bring the lever D, plate I and holdingplateQ, back to the original positions, the finished link falling of its ownweight into a box placed beneath the machine, and the instant the cam 0passes the arm (l of the lever D the rack (I will release the bell-cranklever E, whereupon the spring \V will act to return the bell-crank,collar It, and twister F to their original position, ready to repeat theoperation. There will be several mandrels K, of different sizes, witheach machine, and the mandrels will be interchangeable with each other,so that links of various sizes may be made upon the same machine. Theend of the main arm d" of the lever D is supported upon the bridge orarm A", forming a part of the main frame A, which arm guides thecutting-lever in its movement and takes the down-thrust of the cam c,and the end of this arm (1 is provided with the roller (1 to take thefriction of the cam c. The stationary cutter and guide M is tempered itswhole length, and is so held in the machine that it may be readily takenout and ground and properly adjusted back in the machine,so that aperfectly square and smooth out of the links may always be effected,insuring a perbination with the disk J, made fast to the shaft,

and the gear-wheel I, placed loosely upon the shaft, the disk and gearwheel being provided with clutching and releasing mechanism, wherebycontinuous rotary motion of the gear-wheel I will impart an intermittentrotary motion to the disk, shaft, and mandrel, substantially as and forthe purposes set forth.
